Hello To,
When you reach Combat 5, you should see the capship crafting missions appear. They require various ores, like lanthanic, pentric, heliocene, and some more common ones. The mining requirements are not the most demanding part of fulfilling the missions. Hauling raw materials and semi-finished components through grey space is.
Two of our more dedicated miners are Ecka Estenk and lluvia acida. I have no idea what they're planning to do with all the ore they have stored, but I'm sure they would be happy to discuss it with you!
